Patented Sept. 14, 1943 MULTIPLE GLASS SASH Christian M. Verhagen, Elkhart, Ind., assignor to *The Adlake Company, Chicago, 11]., a corporation of Illinois Application August 1, 1941, Serial No. 405,052

7 Claims.

The purpose of this invention is to provide a. double glass sash of improved construction which is comparatively inexpensive to manufacture, is easy-to put together and take apart, efiectively seals the edges of the panes of glass, and prevents any appreciable conduction of heat from one side of the sash to the other.

While the foregoing statements are indicative in a general way of the nature of the invention, other more specific objects and advantages will be evident to those skilled in the art upon a full understanding of the improved sash construction.

A preferred embodiment of the invention is presented herein for the purpose of exemplification, but it will of course be appreciated that the invention is susceptible of being incorporated in other structurally modified forms coming equally within the scope of the appended claims,

In the accompanying drawing:

Fig. 1 is a perspective view of one corner of a double glass sash constructed in accordance with the invention;

Fig. 2 is a transverse section through one of the rails of the sash, taken on the line 2--2 of Fig. 1; and

Fig. 3 is a separated perspective view showing short sections of the several parts in unassembled condition.

The particular sash shown in the drawing is I provided with two panes l0 and H of glass, but it will of course be understood that the sash features hereinafter described are equally applicable to constructions employing more than two panes of glass.

The sash rails are each characterized by a center strip l2 of rectangular cross section. The strip l2 serves as an insulator in the assembly and may be composed of any suitable insulating material, such as hard rubber, hard fiber, or the like. The sash rails are each also characterized by a pair of side plates [3 and M which are located at opposite sides of the center strip i2. These side plates may advantageously be of extruded aluminum construction.

The side plate i3 is provided at its outer edge with a thin rib l5 which extends laterally into engagement with the center strip l2 at the outer chamber l! which is closed oil by the adjacent face of the center strip l2. The side plate I4 is provided with corresponding ribs l8 and I9 and a corresponding air chamber 20.

The above described parts are clamped securely together by screws M which pass through apertures in the center plate I! and engage within threaded apertures in the rib 16 of the side plate l3. The side plates l3 and M are joined integrally or in any other way at their ends with similar side plates, to complete the rectangular form of the sash.

The edges of the panes l0 and ll are mounted in grooves 22 and 23 formed in a glazing strip 24, The glazing strip '2 is made of soft rubber and is positioned between the inner portions 25 and 26 of the side plates. l3 and M, in abutment with the adjacent edge of the center strip l2 and the adjacent faces of the ribs i5 and I9. The glazing strip 243 when uncompressed is somewhat wider than the distance between the inner portions 25 and 26 of the side plates, with the result that when the side plates are clamped tightly together on the center strip H by the screws 2i the glazing strip will be compressed tightly against both panes to space them apart and at the same time eifectively seal them.

With this improved sash construction the parts l2, l3 and M can be easily and quickly separated from each other, to install or remove either or 1. In a sash, a pair of metal side plates provided with confronting ribs adjacent their outer edges and other confronting ribs intermediate their inner and outer edges, an insulating strip positioned between the side plates in engagement with the ribs, a resiliently compressible glazing strip'clamped between the inner edges of the side plates inwardly of the inner edge of the insulating strip, two or more spaced panes of glass supported by the glazing strip, and means for clamping the side plates against the insulating strip with the glazing strip compressed between the inner edges of the side plates by the action of said clamping means.

2. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, a resiliently compressible glazing strip clamped between the inner portions of the side plates adjacent the inner edge of the insulating strip, two or more spaced panes of glass separated by the glazing strip, said insulating strip solidly abutting the side plates at points adjacent both the outer and inner edges of the insulating strip, and means intermediate said points for clamping the side plates against the insulating strip with the glazing strip resiliently compressed between the inner edges of the side plates by the action of said clamping means.

3. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, a resiliently compressible glazing strip clamped between the inner portions of the side plates adjacent the inner edge of the insulating strip, two or more spaced panes of glass separated by the glazing strip, said insulating strip solidly abutting the side plates at points adjacent both the outer and inner edges of the insulating strip, and means intermediate said points for clamping the side plates against the insulating strip with the glazing strip resiliently compressed between the inner edges of the side plates by the action of said clamping means, said clamping means consisting of screws which extend through apertures in one of the side plates and apertures in the insulating strip into threaded apertures in the other side plate.

4. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, said side plates forming between the inner portions of the same a single glazing groove wide enough for the'accommodation of two or more panes of glass, at resiliently compressible glazing strip clamped in the glazing groove formed between the inner portions'of the side plates inwardly of the inner edge of the insulating strip, two or more spaced panes of glass mounted in and separated by the glazing strip, and means for clamping the side plates solidly against the insulating strip with the glazing strip resiliently compressed between the inner edges of the side plates by the action of said clamping means.

5. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, said side plates forming between the inner portions of the same a single glazing groove wide enough for the accommodation of two or more panes of glass, a resiliently compressible glazing strip clamped in the glazing groove formed between the inner portions of the side plates inwardly of the inner edge of the insulating strip, two or more spaced panes of glass mounted in and separated by the glazing strip, and means for clamping the side plates solidly against the insulating strip with the glazing strip resiliently compressed between the inner edges of the side plates by the action of said clamping means, the outer edge of said insulating strip being substantially flush with the outer edges of the side plates, and forming with the side plates a single self-contained sash rail of substantially rectangular cross section.

6. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, said side plates forming between the inner portions of the same a single glazing groove wide enough for the accommodation of two or more panes of glass, a resiliently compressible glazing strip clamped in the glazing groove formed between the inner portions of the side plates inwardly of the inner edge of the insulating strip, two or more spaced panes of glass mounted in and separated by the glazing strip, and means for clamping the side plates solidly against the insulating strip with the glazing strip resiliently compressed between the inner edges of the side plates by the action of said clamping means, said insulating strip solidly abutting the side plates at points adjacent the outer and inner edges respectively of the insulating strip, and said side plates'being recessed away from the insulating strip intermediate the points of abutment.

7. In a sash, a pair of metal side plates, an insulating strip positioned between the outer portions of the side plates in engagement with the latter, said side plates forming between the inner portions of the same a single glazing groove wide enough for the accommodation of two or more panes of glass, a resiliently compressible glazing strip clamped in the glazing groove formed between the inner portions of the side plates inwardly of the inner edge of the insulating strip,
